It would be interesting to compare what the raw controls can dig out of the X-OCN to what can be achieved using Base Grade in Baselight 5.0. That responds in many ways more like raw controls than traditional grading operators. There is a limit to what can be done differently "in the deBayer". Most raw processing is in fact done with RGB (or sometimes XYZ) image data, and could be reproduced with the appropriate maths applied to ACES linear data.

ACES EXRs could be loaded into the free version of Prelight to test this.
